  • R&S RTM3004 Update – F/W 1.600 & K37 Spectrum Analysis Option

    The Rohde & Schwarz RTM3004 which I was fortunate enough to RoadTest has been a very capable and versatile instrument. Aside from doing serious work with it now that I’ve been working from home, it even featured in a number of “fun” posts such as my …

  • It’sa me, Oscilloscope! - Making Music with a 'scope?

    Even though I’m about to leave on a month-long holiday, I decided to spend a little time to put together a short project for element14’s Project 14 Acoustics Challenge. I was inspired by a Christmas video where someone used an oscilloscope’s arbitrary…

  • R&S RTM3004 Update – F/W 1.400 & K36 Bode Plot Analysis Option

    My original review of the Rohde & Schwarz RTM3004 Oscilloscope went up in July 2018, which identified a number of bugs and functionality issues with the V1.300 firmware that was current at the time. I dutifully reported the issues I had encountered to…

  • R&S RTM3004 RoadTest in Depth – Chapter 3: Usability Aspects

    While on-paper specifications are easy to compare, they only tell part of the story. While a device might be excellent on-paper, it could be difficult to use or have a number of important limitations. In this section, I look at the usability aspects of…

  • R&S RTM3004 RoadTest in Depth – Chapter 4: Protocol Analysis

    Serial interfaces of a number of types are in common use in embedded systems and having the ability to analyse and troubleshoot these communications in the digital domain is one part of a mixed-domain solution. The RTM3004 has the following protocol decode…

  • R&S RTM3004 RoadTest in Depth – Chapter 5: Digital Probe Channels

    Another difference between an ordinary oscilloscope and a mixed domain oscilloscope comes down to the presence of digital input channels. In the case of the RTM3004, the RTM-B1 Mixed Signal option provides 16 digital channels to turn the RTM3004 into…

  • R&S RTM3004 RoadTest in Depth – Chapter 6: Power Analysis

    With modern electronics operating at ever-lower voltages and power efficiency being a prime concern amongst portable electronics, analysis of switching power converters is a common application for high-end oscilloscopes. While the RTM3004 can be used…

  • R&S RTM3004 RoadTest in Depth – Chapter 7: Arbitrary Waveform, Function and Pattern Generator

    The RTM3004 can be more than just an oscilloscope. With the addition of the RTM-B6 Waveform Generator and 4-bit Pattern Generator option, it’s possible to generate regular functions, modulated functions, bit patterns and arbitrary waveforms for testing…

  • R&S RTM3004 RoadTest in Depth – Appendix: Making the Test Set-Up

    In order to test the RTM3004, it was important to have something that generated signals that could be used to challenge the unit. I view testing the unit to be an important part of properly reviewing a product and using the inbuilt demo features or generators…

  • R&S RTM3004 RoadTest in Depth – Chapter 8: PC/LAN Connectivity and Software

    While the previous sections all looked at using the oscilloscope interactively, many users expect to use test equipment via remote control or as part of an integrated testing solution. Fortunately, the Rohde & Schwarz RTM3004 offers a USB device port…

  • R&S RTM3004 RoadTest in Depth – Chapter 2: Unboxing

    Thanks to element14 and Rohde & Schwarz, I’ll be one of the three lucky people from the community to receive a fully-specced-out RTM3004. It was just as exciting as you can imagine, as it’s not every day you get a package like this . As a result, I even…

  • R&S RTM3004 RoadTest in Depth – Chapter 1: Market Survey

    While the RoadTest is mainly concerned with the Rohde & Schwarz RTM3004 oscilloscope, it would be remiss of me to only focus on that particular unit, seeing as test equipment purchases are often a “big ticket” item where it may pay to shop around, especially…
